This message appeared on our system today. It is message number 710 in the "net.math" section. It is a repeat of something that I posted a more than a month ago. Notice that the first part of the message is missing. Two problems: part of the message missing about two month's delay What is going on? The fix for the first problem has been posted around the net. Why is it still happening?

No singular matrices so far. So, I have this question: Given an N by N matrix with integer entries chosen (with replacement) from the set of integers {1, 2, 3, ..., K}, what is the probability, as a function of N and K, that the determinant of the matrix will be zero? -- Lee Dickey (ljdickey@watmath) University of Waterloo -- Lee Dickey, University of Waterloo.
